## Abstract

A bumper assembly includes a bumper beam elongated in a cross-vehicle direction and a bumper that is plastic. The bumper is elongated in the cross-vehicle direction and is affixed to the bumper beam. The bumper beam is rigid relative to the bumper. The bumper defines a cavity enclosed by the bumper. The cavity is elongated in the cross-vehicle direction.

## Claims

### Claim 1

A bumper assembly comprising:
a bumper beam elongated in a cross-vehicle direction;
a bumper that is plastic, the bumper being elongated in the cross-vehicle direction and affixed to the bumper beam, the bumper beam being rigid relative to the bumper;
the bumper defining a cavity enclosed by the bumper, the cavity being elongated in the cross-vehicle direction;
the bumper including an upper beam and a lower beam spaced from the upper beam, the lower beam defining the cavity;
the bumper beam abutting the upper beam; and
a skid plate abutting the lower beam, the lower beam being vehicle-forward of the skid plate.

### Claim 2 (depends on 1)

The bumper assembly of claim 1, wherein the bumper includes an air intake elongated in the cross-vehicle direction.

### Claim 3 (depends on 2)

The bumper assembly of claim 2, wherein the upper beam is above the air intake and the lower beam is below the air intake, the upper beam, and the upper beam and the lower beam being monolithic.

### Claim 4 (depends on 3)

The bumper assembly of claim 3, wherein the bumper incudes lamp compartments between the upper beam and the lower beam.

### Claim 5 (depends on 1)
